Direct System 100lt – Frost & Frost Free – w/ 12 Tubes

Inland and Coastal Areas

This direct system can be used in frost and frost-free locations and where the water quality
is good (less than 600ppm Total Dissolved Solids/Minerals).

The direct system, is where the water to be used in the household (hot water) circulates through the solar vacuum tubes manifold, transferring solar energy into the storage tank of the solar water heater.

This direct system is installed as a Close Coupled System (thermosyphon circulation), where the solar water heater is installed outside on the roof and above the solar vacuum tubes.

The solar water heater has an isolator switch fitted on the front end dome (IPX4 rated) and designed for domestic hot water application in conjunction with an array of solar vacuum tubes.

The two extra water connections required for connecting the manifold above the solar vacuum tubes, and the booster element, ensures that the solar water heater can be used as a conventional electric water heater and as a solar water heater.

The solar water heater thermostat will automatically switch on when the incoming hot water from the manifold above the solar vacuum tubes, has not reached the set temperature setting on the thermostat. This will occur on cloudy days and at night when the water temperature drops in the solar water heater or when hot water is drawn off and cold water enters the solar water heater.
